This dissertation presented the work done towards low frequency study
of a sample of new candidate Galactic Supernova remnants (SNRs).
Details of the observations of this sample of new candidate SNRs, data
calibration, analysis and interpretation were presented. A number of
other sources are visible in the
field of view of
these observations, and the nature of some of these sources was also
discussed. This work constitutes one of the first observations using
the imaging capabilities of the Giant Meterwave Radio Telescope
(GMRT), which is predominantly a low frequency instrument. The GMRT
has only recently come to a stage where it can be used for mapping
complicated fields like the ones studied in this dissertation. This
required system debugging, system parameter measurements, calibration
and understanding of the instrument, which in-turn led to the
development of data analysis techniques and algorithms and related
software. Details of instrumental calibration, debugging, related
software and algorithm development were also presented. A new method
for the computation of polarization leakage using only the
co-polar visibilites was also described. Polarization leakage
manifest themselves as closure errors in the co-polar visibilities
and this method can be used to correct for such closure errors.
